- Tennyson faces a high risk of flooding due to its proximity to the Hawkesbury River and low-lying areas. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
- Bushfire
- Tennyson has a moderate bushfire risk due to surrounding bushland. Hotter, drier conditions are projected to increase the likelihood of bushfires.
- Heat
- Tennyson is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode

- Highest high-risk exposure
- 17.6% of land (bushfire)
Climate Safety Analysis
Tennyson in New South Wales has an overall climate safety rating of High. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Tennyson's climate safety include heat, flood, bushfire. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Tennyson is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
